Title: Improvements in or relating to apparatus for cutting and stacking lengths from a band, ribbon, flattened thin-walled tube or the like
IPC: B26D1/04
Filed: 1955-04-22
Abstract: 768,325. Cutting webs. KUNSTZIJDESPINNERIJ NYMA N.V., [formerly NAAMLOOZE VENNOOTSCHAP KUNSTZIJDESPINNERIJ NYMA]. April 22, 1955 [April 22, 1954], No. 11746/55. Class 31 (1). [Also in Group XVI] Apparatus for cutting a web 3 into lengths comprises two rollers 1, 2 for advancing the web between a reciprocating knife 4 and stationary counter knife 5, and a stacker member 6 for feeding the cut lengths to a stack forming chamber. The knife 4 is provided with extensions 24, 25 which move in guides integral with the counter knife 5, and is reciprocated by means of a cam 15, cam follower 17 and two-armed lever 21. Resiliently mounted on the knife 4 and extending slightly forwardly thereof is a member 8 which serves to clamp the web against a plurality of spring-urged pins 12 mounted in guides 11 on the knife 5. Since the member 8 and pins 12 extend beyond the edges of the knives with which they are associated, they also serve to prevent the sticking of the web to either knife. The knife 4 also carries sheet stacking members 6 which deliver the sheets into a chamber formed by the underside of the knife 5 and a table 23, the position of which may be varied in accordance with the length of the cut sheets required. If a reduction of sheet length is required during operation, however, owing to a reduction in the length of successive printed parts of the web the frequency of cutting may be varied by means of a photo-electric cell. Guide-pins, one of which is shown at 28, are provided above the rollers 1, 2 for moving the web transversely in its plane in the event of misprints being detected by a photo-electric cell. A displaced pile 30 is thus produced which may be readily removed.

Title: Improvements in or relating to detector mechanism for use with sheet-feeding apparatus
IPC: B65H9/06
Filed: 1944-07-04
Abstract: 580,346. Stopping arrangements. BLACKHOUSE, H. T. July 4, 1944, Nos. 12753 and 19727. [Class 100 (ii)] In connection with feeler mechanism for stopping printing &c. machines if a sheet is not fed correctly to the front stops of the machine. of the kind in which the sheets act upon a feeler 9 mounted like a pendulum and in which the feeler prevents movement of a detector member 13 when the feeler is not acted upon by a sheet and so actuates clutch mechanism to stop the machine, the normal movement of the detector 13 is caused to give a further movement to the feeler after it has been moved by a sheet so as to prevent it from interfering with the action of sheet-taking grippers. As shown in Fig. 1, the feeler 9 is normally prevented from moving counter-clockwise by a pin 12 on an adjustable bracket 5 in-which the lever arm 19 for operating the detector 13 is also mounted. A sheet before reaching the front stop 11 moves the feeler 9 clockwise and an arm 10 on the feeler shaft releases the detector 13 which in its motion to the left-engages a hump on the arm 10 and moves the feeler further in a clockwise direction so as to be free of the grippers. The whole mechanism can be adjusted longitudinally of a bar 6 mounted between the machine frames. In a modification the detector 13 acts upon the underside of the pivot 8 of the feeler to effect the movement of the feeler, and in a further modification, Fig. 3, the detector is moved to the right instead of the left and a catch 31 on the arm 10 engages a projection on the underside of the detector when the machine is to be stopped owing to non-engagement of a sheet with the detector 9. The further movement of the feeler is effected by the action of a hook 33 on the detector upon a pin 34 on the feeler 9. In a further modification, Fig. 4, the detector 9 is combined with a caliper device which also stops the machine if two or more sheets are fed at a time. The sheets are fed under a pivoted gauge bar 40 which rests at its forward end on an underlay 41. A hook 42 on the bar 40 is normally free of a tongue 43 depending from the arm 10 of the feeler 9. If double-feed occurs the action of the sheets upon the tongue 43 prevent the normal movement of the feeler 9 to the dotted line position under action of the fed sheet, and this causes stoppage of the machine.
